Astm d 1193 06 (2011)

Designation: D1193 − 06 (Reapproved 2011) Federal Test Method

Standard No. 7916

Standard Specification for

Reagent Water1

This standard is issued under the fixed designation D1193; the number immediately following the designation indicates the year of

original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A

superscript epsilon (´) indicates an editorial change since the last revision or reapproval.

This standard has been approved for use by agencies of the Department of Defense.

1. Scope

1.1 This specification describes the required characteristics

of waters deemed suitable for use with the Standards under the

jurisdiction of ASTM.

1.2 The alphanumeric characters ascribed to water types and

grades are specified in the ASTM Format and Style Manual.

These have been assigned in order of historical precedence and

should not be taken as an indication of a progression in water

purity.

1.3 Four types of waters have been specified, with three

additional grades that can be applied to the four types. The

grade specifications specifically address contaminants of mi￾crobiological origin.

1.4 All applicable ASTM Standards are expected to refer￾ence one or more of these reagent water types where reagent

water is needed as a component of an analytical measurement

process. Where a different water type or grade is needed for an

ASTM Standard, it may be added to this Specification through

the ASTM Standard revision process.

1.5 Although these water types and associated grades have

been defined specifically for use with ASTM Standards, they

may be appropriate for other applications. It is the responsi￾bility of the users of this standard to ensure that the selected

water types or grades are suitable for their intended use.

Historically, reagent water Types I, II, III, and IV have been

linked to specific processes for their production. Starting with

this revision, these types of waters may be produced with

alternate technologies as long as the appropriate constituent

specifications are met and that water so produced has been

shown to be appropriate for the application where the use of

such water is specified. Therefore, the selection of an alternate

technology in place of the technology specified in Table 1

should be made taking into account the potential impact of

other contaminants such as microorganism and pyrogens. Such

contaminants were not necessarily considered by the perfor￾mance characteristics of the technology previously specified.

1.6 Guidance for applications, the preparation, use and

monitoring, storage, handling, distribution, testing of these

specified waters and validation of the water purification system

is provided in Appendix X1 of this document.

1.7 The values stated in SI units are to be regarded as

standard. No other units of measurement are included in this

standard.

1.8 This standard does not purport to address all of the

safety concerns, if any, associated with its use. It is the

responsibility of the user of this standard to establish appro￾priate safety and health practices and determine the applica￾bility of regulatory limitations prior to use.
